2 Claims.

My invention. relates to improvements in mop wringers for use especially in. wringing mops on thestairs.

. The primary object of my invention is to provide. a simply constructed, inexpensive mop wringer for use on a mop. bucket to easily and quickly wring. a mop, or the like, on stairs being cleaned, without subjecting the hands to the injurious eifects of cleaning disinfectants, and/or other similar preparations commonly used in wator for mopping purposes.

Other and subordinate objects, within the purview of my invention, together with the precise nature of my improvements will be readily understood when the succeeding description and claims are read with reference to the drawings accompanying and forming part of this specification.

In said drawings:

Figure 1 is a View in perspective illustrating my improved mop wringer attached to a mop bucket positioned on a stairs ready for use;

Figure 2 is a fragmentary View in vertical section;

Figure 3 is aview in rear elevation of the mop wringer detached;

Figure 4 is a view in plan;

Figure 5 is a view in perspective of the squeeze plate;

Figure 6 is a view in perspective of the rock shaft and crank disks thereon.

Referring to the drawings by numerals, my improved mop wringer, as shown, comprises, as its basic elements, a squeeze frame I for attachment, in a manner presently explained, to a mop bucket 2, and a squeeze plate 3 for cooperation with the squeeze frame I to wring a mop 4 as presently described.

The squeeze frame l, which is preferably formed of light strong sheet metal, is vertically elongated and U-shaped in cross section with substantially parallel sides 5 and an upwardly and outwardly slanting flat front 6, said frame being open at its back. At the back of said frame I, the vertical edges of the sides 5 are undercut, substantially midway of the top and bottom of said frame, to form a pair of vertical slots 1 in said sides 5 fitting downwardly over the rim 8 of the bucket 2, and said sides 5 are provided with leg portions 9 adapted to rest against the inner side of said bucket 2 so that said frame i may be suspended from the rim 8 partway in said bucket 2 and is overbalanced inwardly of said bucket 2 to maintain an upright position therein. When so suspended, the front 6 of said frame l extends 2. Slots. l0. are formed in the front 6 of: said frame" I. and. similar slots l I. in the sides 5'; to permit liquid squeezed: from the mop 41 todrain: quickly int saidbucket 2;

The squeeze plate 3 fits: between the sides & of the. squeeze frame I. loosely in upright. position and, is. L-shaped in vertical; section to provide a bottom lateral flange I 2 extending toward: the front]; ofsaid frame I' at the bottom: edge of said front 6 to support the mop: 4 when the mop strands I3 are interposed. between. saidfront 6 and saidplate 3, A pair-of h-shaped reinforcing bars. M! extend vertically of the? squeeze plate 3 at the. back thereof adjacent opposite sides: of said plate-, and also extend under said flange; l2.

A pair of upright links; I53 are pivotadi at lower ends thereof: on a cross rod: t6 connecting; the lower ends of the legs 9, the upper ends ofti Said links [5 being ivoted; to the lower ends of the reinforcing bars I34 by: pivot? pins '1: with; cotter pins l titherein, said lin-ks I5; providing: forswinging adjustment of said squeeze plate; 3r toward. and from. the front Snot the squeeze. fran iev l In. this connection it isto. be; noted thatthe linksk5; PIE-OI! vide for said movement of said squeeze plate 3 toward the front 6 with the flange l2 below said front 6 so that the said flange will not interfere with movement of said plate 3 close to the front 6 of said frame.

For moving the squeeze plate 3, a transverse rock shaft I9 is rotatably mounted at its ends in the sides 5 back of the squeeze plate 3 and above the slots 1' to dispose the same above the mop bucket 2 and intermediate the top and bottom of said plate 3, preferably below the transverse center of said plate. A handle socket 20 of metal is provided to fit on one squared end 2| of the rock shaft IS in upstanding position with the lower end of a wooden handle shaft 22 fitted therein. A pair of crank disks 23 are suitably fixed eccentrically on the rock shaft l9 adjacent opposite sides 5 of the squeeze frame I and between said sides. A pair of links 24 are pivoted at one end, as at 25, on said disks 23, eccentrically of the rock shaft Hi, to extend forwardly over said rock shaft with the other ends thereof pivoted as at 26, to the reinforcing bars M.

The mop bucket 2 with which my improved mop wringer is specially designed to be used is of a semi-cylindrical type in cross section with a flat side 21 to which said wringer is attached, as described, such a bucket being well adapted for standing on the tread 28 of a stairs with the flat side 2! facing the riser 29 and fitting against the downwardly into the bucket 2 to drain therein. 5 front edge of the next higher tread. When thus positioned, such a bucket 2 is more stable than the usual round bucket and thereby lends stability to the mop wringer.

The manner in which the described mop wringer is operated will be readily understood. By swinging the handle shaft 22 rearwardly until the links 24 rest on the rock shaft 19, the squeeze plate 3 may be moved rearwardly away from the front 6 of the squeeze frame I to open up the mop wringer. The strands l3 of the mop 4 may then be inserted downwardly between. the squeeze plate 3 and said front 6 on the flange l2, and the handle shaft 22 then pulled forwardly thus rocking the rock shaft I 9 and revolving the crank disks 23 so as to thrust the links 24 forwardly and thereby move the squeeze plate 3 toward the front 6, as shown by dotted lines in Figure 2, whereby the strands l3 will be squeezed between said squeeze plate 3 and said front 6 to wring the mop. In this connection, it is to be noted that the links l and 24 provide for downward movement of the squeeze plate 3 during its forward movement whereby said plate 3 exerts a downward squeezing action against the mop strands l3 which facilitate wringing said strands. During the described wringing operation, the bucket 2 may be steadied by'the' hand, or not, as occasion may require.

- The foregoing will, it is believed, sufiice to impart a'clear understanding of my invention, without further explanation.

Manifestly, the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A mop wringer for attachment to the rim of a bucket comprising a frame including an open back and a closed front, and sides adapted to fit downwardly over said rim to support said frame on the rim with said front in upright position, a squeeze'plate in said frame in upright position at the back thereof for movement toward said front to squeeze a mop therebetween, links pivoted to said sides and to the lower end of said plate for supporting said plate and causing the same to move downwardly during movement of said plate toward said front to thereby exert a downward squeezing action against said mop, a swingable handle on said frame, and means operative by said handle to move said plate toward said front.

2. A mop wringer for attachment to the rim of a bucket comprising a frame including an open back and a closed front, and sides adapted to fit downwardly over said rim to support said frame on the rim with said front in upright position, a squeeze plate in said frame in upright position at the back thereof for movement toward said front from a normal position to squeeze a mop therebetween, links pivoted to said sides and to the lower end of said plate for supporting said plate and causing the same to move downwardly during movement of said plate toward said front to thereby exert a downward squeezing action against said mop, a handle swingable on said frame from a normal position, and means operative by said handle to move said plate toward said front comprising a rock shaft, crank disks on said shaft, and links connecting said disks to said plate and overlying and engaging said shaft in the normal position of said plate and handle to establish said position.
